Riverbank Filtration Technology

A Green, Natural Alternative for Pre-treating
Surface Drinking Water

As energy costs for conventional treatment technologies escalate, translating into increases in user rates, alternative pretreatment technologies are being more widely used. Riverbank Filtration (RBF) technology is at the forefront as a method for not only pre-treating existing raw surface water supplies, but also for developing new and sustainable water supplies.

RFB is a natural pre-treatment process that uses the bed of reservoirs, lake or rivers and an adjacent sand and gravel aquifer as a natural filter. RBF can be applied directly to existing surface water reservoirs, streams, lakes, and rivers, and is often now a guiding factor in the hydrogeologic investigation of new source supplies.
